In a brush, in particular for coloring eyelashes or hair, comprising a stem and a number of bristles standing out essentially radially therefrom, the stem being formed by a first leg of a tweezers- or scissors-like arrangement, and a second leg of this arrangement having, at its free end, an abutment for the bristles of the first leg such that in operation, the free outer ends of the two legs enclose between them the eyelashes or hair to be treated. At least one of the two legs (4, 5) being designed as a hollow tube connected with a supply container and having outlets leading to the outside.

BACKGROUND OF THE INVENTION

1. Technical Field of the Invention

The invention relates to a brush, in particular for the coloring of eyelashes or hair, comprising a stem and a plurality of bristles standing out substantially radially therefrom. The stem is formed by a first leg of a tweezers- or scissors-like arrangement. The second leg of this arrangement has, at its free end, an abutment for the bristles of the first leg such that in operation, the free outer ends of the two legs enclose between them the eyelashes or hair to be treated.

2. Prior Art

Brushes of the generic type, for instance in the form of mascara brushes, serve to apply mascara to the eyelashes. The application must be such that the lashes are colored uniformly and prevent application of too much liquid, which would cause clotting or lashes sticking together. In order to prevent the lashes from sticking together partially or entirely, mascara brushes of the generic type exhibit a combing effect in addition to good retention and dispensing capacity. To this end, attempts have been made to equip mascara brushes with different fibers or fibers of different rigidity, part of these fibers excelling in favorable mascara transport properties and the other part of the fibers by advantageous combing effects. However, the properties which seem to be attainable theoretically by such a design do not prevail in practice.

As for the dyeing or coloring of hair of the head, there is also the problem of uniform application, to which is added the fact that the dyeing or coloring agents are comparatively aggressive so that the application has to be accompanied by arrangements being made for the protection of the user's hands and surroundings.

OBJECT AND SUMMARY OF THE INVENTION

It is the object of the invention to embody a brush of the type mentioned at the outset in such a way that the application of the dyeing agent or mascara will be optimized, simultaneously providing for a uniformly attractive appearance of the colored eyelashes or the dyed hair.

According to the invention, this object is attained in that at least one of the two legs is a hollow tube connected with a supply container and provided with outlets that lead to the outside.

Consequently, it is possible to realize a very compact applicator or mascara unit, in which the bristles need not be dipped into the supply container for humidification, but in which the mascara is supplied from within the brush.

In keeping with an advantageous embodiment, it is further provided that a pumping operation is initiated by the two legs being moved relative to each other for liquid to be pumped from the supply container to the at least one brush. To this end, the outside wall of the supply container is at least partially elastic so that any actuation of the tweezers-like arrangement is accompanied by the pumping of liquid. It would also be conceivable to provide a separate pumping arrangement, a membrane or a piston of such a pumping arrangement being activated by the tweezers-like motion via an articulation.

Provision can be made for mascara, make-up removing liquid or hair dyeing agents to be kept in the supply reservoir so that the clamping effect may also serve to make use of increased pressure for the removal of mascara while make-up is removed.

In a very simple embodiment of the mascara brush or unit according to the invention, it can be provided that the two legs consist of wire of a certain intrinsic elasticity, preferably of a U-shaped wire, the legs being formed by the legs of the U.

Finally, provision can be made for the fibers to be fixed in place between intertwisted wire segments in a manner known per se and for the legs to be formed by intertwisted wires.

Favorably, it can be provided that the core of the brush formed by the intertwisted wire segments is again twisted on itself, in particular helically about a linear core available as a permanent component or as an auxiliary member only during manufacture. As a result, the volume is clearly increased and advantageous dispensing properties can be realized in case this embodiment is used as a mascara brush.

It is further possible to provide the core with outlets that communicate with the supply container so that for instance hair dyeing agents can be led directly onto the twisted brush arrangement.

Details of the invention will become apparent from the ensuing description of a preferred embodiment of the invention, taken in conjunction with the drawing. The drawing shows diagrammatic illustrations of various embodiments of brushes according to the invention in the form of mascara brushes or mascara units equipped with such brushes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S) OF THE INVENTION

In the embodiment of FIG. 1, the mascara brush bristles 3 are fixed in place in a manner known per se between two intertwisted wires 1, 2 or wire segments, forming a brush at the free left end of the brush.

No bristles 3 are provided at the rearward end of these wires 1, 2 thus forming a stem there that constitutes a first leg 4 of a tweezers-like arrangement. A second leg 5 is provided having a comb-type abutment element 6 at its free front end. Both legs 4, 5 are retained in a handle 7.

The legs 4, 5 exhibit a certain resilient intrinsic elasticity so that they can be moved toward or away from each other in the direction of the double-headed arrow 8 when held for example between the user's thumb and index finger.

FIG. 2 is a diagrammatic illustration of a mascara unit with a brush according to the invention being used. The upper side of the mascara container 8 has two openings 9, 10, into each of which reaches a leg 4a, 5a. Bristles 3a are disposed at the free outer ends of legs 4a, 5a. The two legs 4a and 5a are replaceably fixed to a handle 11 which serves simultaneously as a closure and is elastic, tending to spread--as outlined by the arrows 12--and being compressible between thumb and index fingers during use. A dividing wall 13 is shown by dashes in the drawing. The wall 13 divides the container 8 into two compartments for different liquids to be stored therein, which may for instance serve to trigger a reaction only during application when the two liquids contact, or to avoid segregration.

FIG. 3 shows a variant of the solution according to FIG. 2, the container 8b being divided by an opening 14 in the central portion and split into two compartments, a leg 4b, 5b having bristles 3b, respectively, being disposed in each compartment. A dividing wall 13b may separate the two compartments in the lower portion. The handle 11b is elastically expansible and serves simultaneously as a closure for opening 16.

In the embodiment of FIG. 4, the bristles 3c are disposed on the intertwisted wire stems 7 replaceably fastened on legs 4c, 5c which are hollow tubes connected with a mascara supply 15 in a container 8c, the mascara being transported for instance by pressure exercised on the at least partially flexible container wall. It is possible to supply only one or both groups of bristles 3c with mascara. As in the embodiments of FIGS. 1-3, at least leg 4c exhibits a certain resilient intrinsic elasticity so that it can be moved toward leg 5c when legs 4c and 5c are held between the user's thumb and index finger. If desirable, leg 5a can also have the same elasticity as leg 4c.

Consequently, it is possible to realize a very compact applicator or mascara unit, in which the bristles need not be dipped into the supply container for humidification, but in which the mascara is supplied from within the brush.

In keeping with this advantageous embodiment, it is further provided that a pumping operation is initiated by the two legs being moved relative to each other for liquid to be pumped from the supply container to the bristles. To this end, the outside wall of the supply container is at least partially elastic so that any actuation of the tweezers-like arrangement is accompanied by the pumping of the liquid.

Further, either one or both of the two hollow legs 4c and 5c have an outlet 6c to the outside and to bristles 3c wherein mascara make-up remover or hair dye from container 8c can be delivered to bristles 3c by placing pressure on the container 8c.
